Forged Fittings
Union
Flangeman Steel Worldwide Pvt Ltd manufactures and supplies high-quality Forged Fitting Unions, designed to connect two pipes in a piping system while allowing easy disassembly for maintenance or replacement. Unlike standard couplings, unions can be disconnected without cutting the pipe, making them ideal for systems that require frequent servicing or inspection.
Manufactured using advanced closed-die forging technology, our forged unions provide superior strength, leak-proof performance, and long-term durability in high-pressure and high-temperature applications.
Types of Forged Unions
Threaded Union – Designed for threaded pipe connections (NPT / BSPT)
Socket Weld Union – Used in high-pressure systems requiring welded connections.
Features of Forged Fitting Union
Flangeman Steel Worldwide Pvt Ltd’s forged unions are precision-engineered for reliable and secure pipe connections. Manufactured through hot forging, these fittings offer superior mechanical strength, excellent grain structure, and enhanced resistance to pressure and temperature. The union design allows convenient maintenance and system modification without cutting or welding the pipeline. Available in carbon steel, stainless steel (304/316), and alloy steel, these fittings provide excellent corrosion resistance and long service life. Smooth internal finishing ensures minimal pressure drop and efficient flow performance, while threaded and socket weld options ensure secure and leak-proof joints in demanding industrial environments.
